Leftover Salmon helped build the DNA of jamgrass — that wild, joyful collision of bluegrass purity and rock-and-roll abandon. Formed in Boulder, Colorado, they became pioneers of the modern festival scene, blending banjo fire, Cajun spice, swamp-rock swagger, and improvisational freedom into music that feels like a road-trip, river-run, and back-porch party all at once. Over decades of touring, lineup shifts, triumphs, and reinventions, they’ve remained a band of the people — communal, untamed, generous with the groove. Whether electrifying Red Rocks, stirring up Telluride, or picking deep into the night, Leftover Salmon keep the tradition alive by refusing to stand still, carrying forward a legacy built on strings, sweat, spontaneity, and pure, Colorado-grown joy.
